Browser Use Cloud Reference

Reference docs for the Cloud REST API, SDKs, and integration patterns. Read the relevant file based on what the user needs.

Choose a starter

Hosted task in, result out: use the V4 SDK runs resource in references/api-v4.md.
Your existing agent needs a browser: use the V4 SDK browsers resource or REST/CDP, then explicitly stop the browser.
Local framework development: use the open-source browser-use skill, not Cloud SDK calls.

Eligible new Google, GitHub or Microsoft signups get a one-time $15 Cloud credit. No card required; email/password signups do not qualify. Pricing and eligibility. Use gpt-5.6-luna for the free starter; paid-only models need a top-up.

Reuse BROWSER_USE_API_KEY, or guide the user through Cloud signup and key creation. Keep keys server-side, never in prompts or client bundles.

Critical Notes

Use v4 for new hosted-agent integrations. Keep v2 or v3 only when maintaining an existing integration or using a resource not yet wrapped by the v4 SDK.
Cloud API base URL: https://api.browser-use.com/api/v2/ (v2), https://api.browser-use.com/api/v3 (v3), or https://api.browser-use.com/api/v4 (v4)
Auth header: X-Browser-Use-API-Key: <key>
Get API key: https://cloud.browser-use.com/new-api-key
Set env var: BROWSER_USE_API_KEY=<key>
Cloud SDK: uv pip install browser-use-sdk (Python) or npm install browser-use-sdk (TypeScript)
Python v2: from browser_use_sdk import AsyncBrowserUse
Python v3: from browser_use_sdk.v3 import AsyncBrowserUse
Python v4: from browser_use_sdk.v4 import BrowserUse or AsyncBrowserUse
TypeScript v2: import { BrowserUse } from "browser-use-sdk"
TypeScript v3: import { BrowserUse } from "browser-use-sdk/v3"
TypeScript v4: import { BrowserUse } from "browser-use-sdk/v4"
SDK 3.11.3 or newer exposes browsers.create and browsers.stop in the v4 namespace, alongside the v4 REST /browsers resource. Always stop a browser explicitly; closing CDP does not stop billing.
